据普氏能源资讯7月24如休斯顿报道，美国能源信息署（EIA）周三公布的统计数据显示，在截至7月19日的一周里，美国的丙烯库存量连续第4周下降，下降到了408.5万桶，这是今年以来的最低水平。

统计数据显示，上周非燃料使用的丙烯库存量比前一周减少了23.9万桶，但上周仍比去年同期增加了147.5万桶。

在美国丙烯库存量周比下降的同时，炼油厂的利用率略有下降，这是由于飓风“巴里”(Barry)造成的，飓风“巴里”把炼油厂的利用率下降了1.3%，至93.2%。

消息人士称，最近巴斯夫-道达尔的裂解装置、德州阿瑟港和Flint Hills资源公司在休斯顿的丙烷脱氢装置的转场以及Enterprise产品合作伙伴公司在在蒙特贝尔维的PDH厂的临时性停运给最近几周对丙烯供应施加了压力并使供需保持了平衡。

US EIA says propylene stockpiles fall on week; lowest in 2019

US propylene stocks fell for the fourth consecutive time to 4.085 million barrels in the week ended July 19, to the lowest level this year, according to Energy Information Administration data released Wednesday.

Non-fuel use propylene stocks fell 239,000 barrels from a week earlier, though last week's stocks were still up 1.475 million barrels from the same time a year earlier.

The week-on-week drop in US propylene stocks came alongside slightly lower refinery utilization rates, due to Hurricane Barry, which dropped 1.3% to 93.2%.

Sources said that recent turnarounds at BASF-TOTAL's cracker and in Port Arthur, Texas, and at Flint Hills Resources' propane dehydrogenation plant in Houston, along with the temporary outage at Enterprise Products Partners' PDH plant in Mont Belvieu, have put pressure on propylene supply in recent weeks and have kept supply and demand in balance.
